Android控件开发之TimePicker

 TimePicker介绍

   TimePicker也继承自FrameLayout类. 时间选择控件向用户显示一天中的时间

  (可以为24小时,也可以为AM/PM制),并允许用户进行选择.如果要捕获用户修改的时间数据事件,

  便需要为TimePicker添加OnTimeChangedListener监听器

1.重要方法

setCurrentMinute(Integer currentMinute) 设置当前时间的分钟
getCurrentMinute()                      获取当前时间的分钟
setEnabled(boolean enabled)             设置当前视图是否可以编辑。
m_TimePicker.setIs24HourView(true);     设置为24小时制显示
setOnTimeChangedListener(TimePicker.OnTimeChangedListener onTimeChangedListener)当时间改变时调用
           

　　

2.实例： 　　

timePicker = (TimePicker)findViewById(R.id.timePicker);
timePicker.setCurrentHour(16);
timePicker.setCurrentMinute(10);
updateDisplay(16,10);
timePicker.setOnTimeChangedListener(this);

<TimePicker 
    android:id="@+id/timePicker"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"/>

<TextView
    android:id="@+id/textView"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center_vertical"/>

</LinearLayout>
           

Java源码

package com.sx.TimePicker;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
import android.widget.TimePicker;
import android.widget.TimePicker.OnTimeChangedListener;

public class TimePickerActivity extends Activity 
{
    private TimePicker timePicker = null;
    private TextView   textView   = null; 
	
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        timePicker = (TimePicker)findViewById(R.id.timePicker);
        textView   = (TextView)  findViewById(R.id.textView);
        
        timePicker.setOnTimeChangedListener(new OnTimeChangedListener()
        {
		@Override
		public void onTimeChanged(TimePicker view, int hourOfDay, int minute)
		{
			textView.setText("你选择的时间是: " + hourOfDay + "时" + minute + "分");
		}
        });    
    }
}
           

 TimePickerDialog

 以对话框形式显示时间视图

Java源码

package com.sx.TimePickerDialog;

import java.util.Calendar;

import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.TimePickerDialog;
import android.os.Bundle;
import android.widget.DatePicker;
import android.widget.TimePicker;

public class TimePickerDialogActivity extends Activity 
{
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        		      		
        final Calendar calendar = Calendar.getInstance(); 
        final int hour   = calendar.get(Calendar.HOUR_OF_DAY);
        final int minute = calendar.get(Calendar.MINUTE);   

        final TimePickerDialog timePickerDialog = new TimePickerDialog(this, setting, hour, minute, true);
        timePickerDialog.show();
    
    }

	//当点击TimePickerDialog控件的设置按钮时，调用该方法  
	TimePickerDialog.OnTimeSetListener setting = new TimePickerDialog.OnTimeSetListener()  
	{
		@Override
		public void onTimeSet(TimePicker view, int hour, int minute) 
		{
			
		} 
	  
	};      

}
